Storms in Slidell on Thursday brought 3.86 inches of rain to the city, and in some parts there were up to 4.8 inches, Mayor Freddy Drennan noted in a prepared statement. Drennan added that the National Weather Service is predicting a 90 percent chance of rain today could bring an additional 2 to 4 inches of rainfall to town.

Municipal crews have cleaned drainage pumps, and they are cleaning catch basins, Drennan said. The pumps will be manned throughout the rainfall, but Slidell's systems cannot handle 6 to 8 inches of rain "in a 24- to 36-hour period," the mayor warned.

"Yesterday, we had a lot of rain come through Slidell, and some homes came close to flooding," he said. "The ground is saturated, and our drainage systems are still inundated from that rain."

Drennan asked residents to stay off roadways as much as possible and avoid driving through flooded streets.

"Your vehicle could stall, and you could push water into people's homes," he said.
